eBay SOAP API - 缺少 SOA 操作名称标头

Question

我试图调用 eBay 的 findItemsByKeywords 方法，我得到

服务器引发故障：“缺少 SOA 操作名称标头”

我的代码如下：

from config import *

# url = 'http://developer.ebay.com/webservices/latest/ebaySvc.wsdl'
# url = 'http://svcs.ebay.com/services/search/BestMatchItemDetailsService/v1?wsdl'
url = 'http://developer.ebay.com/webservices/finding/latest/FindingService.wsdl'

from suds.client import Client
import logging
logging.basicConfig()
client = Client(url)

from suds.sax.element import Element
ns1 = ('ns1', 'http://www.ebay.com/marketplace/search/v1/services')
app_id = Element('X-EBAY-API-APP-ID', ns = ns1).setText(EBAY_API_APP_ID)
operation_name = Element('X-EBAY-SOA-OPERATION-NAME', ns = ns1).setText('findItemsByKeywords')
api_version = Element('X-EBAY-API-VERSION', ns = ns1).setText(EBAY_APP_VERSION)
site_id = Element('X-EBAY-API-SITE-ID', ns = ns1).setText(EBAY_API_SITE_ID)
encoding = Element('X-EBAY-API-REQUEST-ENCODING', ns = ns1).setText('SOAP')
service_name = Element('X-EBAY-SOA-SERVICE-NAME', ns = ns1).setText('FindingService')
client.set_options(soapheaders = [app_id, operation_name, api_version, site_id, encoding, service_name]) 

print client.service.findItemsByKeywords(keywords = 'book')

它打印：

Answer 1

使用 ebay-python，eBay API 的非官方 python 包装器。它非常容易使用并且有效。如果您想使用自己的请求，您还可以查看有关如何构造请求的源代码。

Answer 2

我在尝试做同样的事情时遇到了一些 vb.net 代码的错误，结果证明我只是使用了错误的 AppID。我使用的是带有沙箱 url 的实时版本，切换它后就没有问题了。

Answer 3

我使用了这段代码并且它有效

headers={'X-EBAY-SOA-OPERATION-NAME':'findItemsByKeywords',
                'X-EBAY-SOA-SECURITY-APPNAME': 'your-key'}

client = Client(url,headers=headers)
